Interactive Fuzzy Programming for Two-Level Linear Fractional Programming Problems

Abstract

This paper presents interactive fuzzy programming for two-level linear fractional programming problems. In our interactive method, after determining the fuzzy goals of the decision makers at both levels, a satisfactory solution is derived efficiently by updating the satisfactory degree of the decision maker at the upper level with considerations of overall satisfactory balance between both levels. An illustrative numerical example is provided to demonstrate the feasibility of the proposed method.
